Abstract :
The objective of this work is the study and the realization of a photovoltaic conversion chain which consists mainly of a solar panel, a power converter controlled by a signal pulse width modulation (PWM), generated by a microcontroller and an electric load. For develop this work, we carried a chopper Buck we achieve a chopper Buck and different associated cards: cards of measurement, protection and control based on the PIC 18F4550. This one generates a PWM control signal to 10 KHz frequency, with variable duty cycle. A system practical validation is performed, which experimental results showed a good functioning of the achieved system with a satisfactory yield.
